1. A brake control device for a vehicle comprising a plurality of brakes which are respectively installed on wheels, comprising:
an auto leveling sensor which senses a load state of the vehicle according to a change in an angle;
a control unit which calculates a correction value according to the load state of the vehicle sensed by the auto leveling sensor;
an electronic brake booster which corrects a predetermined braking power set according to a brake pedal force with the calculated correction value so that the braking operation of each brake is made; and
a speed sensor which senses a deceleration rate of the vehicle upon braking operation of the brake according to the correction value;
wherein when the sensed deceleration rate exceeds a predetermined deceleration rate, the electronic brake booster ignores the correction value so that the braking operation of each brake is made with the predetermined braking power set according to the brake pedal force.
